简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 Cm}2 >eH
M^FY6TT4O 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: MY&Jdmga enableservice('AutomationServer', true) yK~=6^M enableservice('AutomationServer') w:~*wv -fR:W{u 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 ZO0 Ee1/ W yL+HB} 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: tK#R`AQ 1. 在FRED脚本编辑界面找到参考. \;LDE`Q_x 2. 找到Matlab Automation Server Type Library P]_d;\
